I did a quick search on the HKS website about the exhaust but I came up with nothing. Does anyone know if the coating on the pipping is rust proof like the Apexi N1? I found a great price on the catback but I'm not going to buy it if it's going to rust out on me. Thanks in advance.

 

I have the HKS Hipower, and just went through 1 winter with it.
I have some rust at the welds on the canister hangers. It's very little tho.
The piping's coating is an aluminized coating.

Exhaust Warranty

Q: I bought the drager exhaust for my supra three years ago and noticed only a day ago that the exhaust piping was starting to rust through. Are these mufflers covered under your four year warranty? I dont think that I have the receipt but I would have to look around for it. Any help with this question would be appreciated. Thanks!

A: Only the full stainless versions are covered under the 4 year warranty. The Drager, which is stainless muffler with aluminized piping) is covered under the 1 year warranty. We havent seen many of the non-full stainless systems have issues, unless there was scrapping or impacts onto the piping. Regardless, If you like, you may still contact the dealer it was purchased through to have it address. From there, the dealer will contact thier rep here at HKS USA and see if there is something we may do to assist you in this situation.




Personally. I like the HKS and their company. But I think that maybe a full stainless exhaust system would be better.

If anything happens to my HKS, I'm goin Blitz.

 

Thanks for the info. I actually changed my mind earlier today. I switched to the JIC Magic 505S Sus stainless. Got a smokin deal on it that I couldn't pass up. I'm all set with having my exhaust rot out in only a year. I'm sorry to hear that bro.
